Sleeping Bag Care

Why do we encourage proper care of Marmot clothing and gear?

Because you have invested in (or are thinking about investing in) one of the most technically advanced pieces of apparel or equipment you'll ever own and we want to make sure you have the information you need to protect and care for your purchase. Proper care assures you will optimize the performance of your Marmot product and maximize its service-life.

  • Hand wash warm, 105 degrees Fahrenheit or 40 degrees Celsius or machine wash Warm, Gentle cycle in a front load washer only
  • If you need to use a detergent, only use powdered form
  • Rinse thoroughly, do not wring your sleeping bag
  • Hang dry or tumble dry on low heat. If tumble drying a down bag, toss a couple of clean tennis balls in the dryer to help re-loft the bag
